[PATCH 7/9] arm64: dts: renesas: Add compatible properties to AR8031 Ethernet PHYs

[Geert Uytterhoeven]

Add compatible values to Ethernet PHY subnodes representing Atheros
AR8031 PHYs on RZ/G2 boards.  This allows software to identify the PHY
model at any time, regardless of the state of the PHY reset line.
